Tiivistelmä
A large amount of energy to provide high temperature and high pressure are usually needed in the chemical reaction and separation process of traditional synthesis methods, which results in serious energy waste. However,click chemistry reactions, which have some unique advantages such as high efficiency, high reaction speed and mild condition, are expected to address these challenges. In this paper, a new type star-shape tetramine was synthesized by Thiol-ene click reaction of pentaerythritol tetraacryalte (PET4A) and cysteamine. The obtained star-shape tetramine could be used as an intermediate of dendrimers. In this reaction, PET4A was synthesized by the esterification of pentaerythritol and acrylic acid. IR and 1H NMR were used to characterize the structure of the obtained products.
